Orbit and dynamics
Between its closest point (0.851 AU) and its farthest (1.061 AU), the heliocentric distance changes by 0.21 AU over every revolution.
One full revolution takes 0.94 yr (342 days), computed from the semi-major axis of 0.956 AU.
An eccentricity of 0.11 makes the orbit moderately elongated.
The orbital plane is tilted 9.75° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 34 km/s at perihelion and falls to 27.3 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
The measured diameter is 0.04 km, a value from direct size determination rather than from brightness alone.
A geometric albedo of 0.234 points to a comparatively bright, reflective surface.
Observation record and orbit quality
Astrometry from 145 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4636 arcseconds.
Condition code U = 1 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.
About these computed values
Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
